The Ultimate Guide to Understanding the Different Parts of the Triceps Muscle
The three heads of the triceps muscle are the lateral head, the long head, and the medial head. Each head originates from a different part of the shoulder blade and humerus bone and joins together at the elbow. The lateral head is located on the outside of the arm, the long head on the back of the arm, and the medial head towards the inside of the arm. These three heads work together to extend the arm and straighten it at the elbow.
In this article, we will dive deeper into each head’s anatomy and functions, including the muscle fibers that make up each head and the exercises that target each specific head. Whether you are a beginner or a professional athlete, understanding the anatomy of the triceps muscle is essential for building strength, improving arm extension, and preventing injury.
The Three Heads of the Triceps Muscle
The triceps brachii muscle, commonly known as the triceps, is a three-headed muscle located at the back of the upper arm. Each head of the triceps originates from different parts of the humerus bone and scapula bone. The three heads join together at a common tendon and insert on the olecranon process of the ulna bone, allowing for the extension of the elbow joint.
The long head of the triceps originates from the infraglenoid tubercle of the scapula bone, while the lateral head originates from the posterior humerus above the radial groove. The medial head has a smaller origin site on the posterior humerus, just below the radial groove. The three heads work together to allow for the extension of the elbow joint, but also play different roles in other movements.
- The long head assists in shoulder extension and adduction.
- The lateral head assists in shoulder adduction and horizontal abduction.
- The medial head assists in shoulder adduction and stabilization.
Overall, understanding the three heads of the triceps muscle can help in developing an effective workout routine, targeting each head to achieve optimal results.
Functions of the Triceps Muscle
The triceps muscle is responsible for a variety of functions that are essential for the proper functioning of the upper arms and shoulders. Here are some of the primary functions of the triceps muscle:
- Extension of the elbow: The triceps muscle is responsible for the extension of the elbow joint, which means it is responsible for straightening the arm.
- Stabilization of the shoulder joint: The triceps muscle helps stabilize the shoulder joint during activities like bench pressing and push-ups.
- Assistance with pulling movements: The long head of the triceps muscle assists with pulling movements, like when you pull yourself up during a chin-up exercise.
- Assistance with pushing movements: The triceps muscle is also involved in pushing movements, like when you push yourself away from a wall during a wall push-up exercise.
Overall, the triceps muscle is an incredibly important muscle group that is involved in a wide range of activities. By strengthening your triceps, you can improve your performance in many different exercises and activities, while also reducing your risk of injury.

This article is a must-read for anyone looking to improve their triceps muscle development. The clear and concise explanations, along with the helpful diagrams, make it easy for even beginners to understand. I particularly appreciated the section on the long head of the triceps, as this is often a neglected area during workouts. The article highlights the importance of targeting each part of the triceps muscle for overall strength and definition. However, I do have some suggestions for improvement. It would have been beneficial to include suggested exercises for each specific part of the muscle, as this would provide readers with a more comprehensive plan for their workouts. Additionally, some examples of common mistakes to avoid during triceps exercises would be useful. Overall, I highly recommend this article to anyone looking to improve their triceps muscle development.
